The present invention concerns a partition construction for subdividing a building space including interconnected frames and covers for the frames, and more particularly concerns a cover panel attachment system for the partitions.
In new building constructions, components of wall and partition systems are ordered so that, when interconnected and assembled, they divide the building space into a predetermined arrangement of offices, work areas, and other specialized areas. However, as businesses continue to evolve and the office area undergoes rearrangement, the components are often not as flexible as desired, such that the existing components limit the rearrangement unless new components are ordered. Such new components are expensive, delay the rearrangement, and often are not even available, such as when a particular upholstery for covering the component has been discontinued. Sometimes removable covers are used to cover partition frames. One advantage of removable covers is that, when a corner of one is damaged, it can be interchanged with a new cover, or another removable cover that is in a less visible location. However, unless all of the partition frames are the same size, the removable covers must be interchanged only with other removable covers that are the same size. In addition to the above, architects and office designers are constantly looking for novel constructions that provide novel and distinctive appearance, but that are flexible enough to accommodate both modernistic and more conservative appearance. Furthermore, removable covers allow interiors of the partitions to become accessible for routing utility, power or signal distribution systems through the partitions. However, removable covers can allow light and/or sound to pass through a wall of the partition, thereby interfering with the work environment of adjacent work areas.
Accordingly, an apparatus solving the aforementioned disadvantages and having the aforementioned advantages is desired.
One aspect of the present invention is to provide a partition for open building space and the like having a frame including at least one substantially horizontal surface. A cover member is configured to enclose at least a portion of the frame. The cover member includes attachment members configured to connect the cover member to the frame. A seal is attached to the cover member and includes a resilient flap which engages the substantially horizontal surface of the frame to inhibit the passage of acoustical and/or optical energy through the partition.
Another aspect of the present invention is to provide a cover panel for a partition of the type having a frame with a horizontal surface. The cover panel includes a cover member and a seal. The cover member is configured to enclose at least a portion of the frame. The cover member includes attachment members configured to connect the cover member to the frame. The seal is attached to the cover member, and includes a resilient flap configured to engage the horizontal surface of the frame when the cover member is connected to the frame. The seal inhibits the passage of acoustical and/or optical energy through the partition.
In yet another aspect of the present invention, a method of removing a cover member from a frame is provided. The cover member includes attachment members connecting the cover member to the frame. The attachment members include a detent for connecting a portion of the attachment members to the frame. The frame includes a flange located adjacent an edge of the cover member when the cover member is connected to the frame. The method includes the steps of providing a tool having a notch, inserting the tool between the flange and the edge of the cover member, rotating the tool such that the edge of the cover member is located within the notch of the tool, depressing the detent with the tool, and disconnecting the attachment members from the frame.
The principal objects of the present invention include providing an improved cover panel attachment system for partition panels. The cover panel attachment system allows covers having various configurations to be replaced and/or substituted for existing covers without altering the configuration of the partition frames. The cover panel attachment system also can be used to provide an acoustic and/or optical barrier for adjacent workspaces separated by the cover panel. The cover panel attachment system is efficient in use, economical to manufacture, capable of a long operable life, and particularly adapted for the proposed use.
These and other features, advantages and objects of the present invention will be further understood and appreciated by those skilled in the art by reference to the following specification, claims and appended drawings.
For purposes of description herein, the terms "upper," "lower," "right," "left," "rear," "front," "vertical," "horizontal," and derivatives thereof shall relate to the invention as orientated in FIG. 1. However, it is to be understood that the invention may assume various alternative orientations, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.
The reference number 10 (
In the illustrated example, the frame 12 (
The illustrated compound middle frame cross-member 30 (see
In the preferred embodiment, the frame 12 includes an oval-shaped window 48 (
In the illustrated example, the cover member 16 (
In the preferred embodiment, the intermediate L-shaped flange 64 of each of the upper channel member 62 and the lower channel member 65 includes a pair of slots 70 adjacent each side edge of the intermediate L-shaped flange 64. The pair of slots 70 in the upper channel member 62 are preferably slanted downwards towards each other as they approach the bottom of a vertical surface of the intermediate L-shaped flange 64 of the upper channel member 62. Likewise, the pair of slots 70 in the lower channel member 65 are slanted upwards towards each other as they approach the top of a vertical of the intermediate L-shaped flange 64 of the lower channel member 65. Each intermediate L-shaped flange 66 also includes a short slot 72 in the horizontal surface and the vertical surface of the L-shaped intermediate flange 66 between each of the pair of slots 70. Each attachment member 18 is inserted into one of the pairs of slots 70 to connect the attachment members 18 to the cover member 16. The pair of slots 70 are preferably slanted to assist in properly orientating the attachment member 18 in the slots 70, although the slots 70 could be parallel. Furthermore, the seal 20 is connected to the lower flange 68.
The illustrated seal 20 (
When the seals 20 are placed onto the channel members 62 and 65 of the cover member 16 in the preferred embodiment, the resilient flap 22 of the seal 20 of the upper channel member 62 would face upward and the resilient flap 22 of the seal 20 of the lower channel member 65 would face downward. Furthermore, when the illustrated cover member 16 is connected to the frame 12, the resilient flap 22 of the seal 20 of the upper channel member 62 would engage the horizontal surface 14 on the bottom face 34 of the top frame cross-member 24 or the horizontal surface 14 of the bottom face 46 of the compound middle frame cross-member 30. Likewise, the resilient flap 22 of the seal 20 of the lower channel member 65 would engage the horizontal surface 14 on the top face 38 of the bottom frame cross-member 26 or the horizontal surface 14 of the top face 44 of the compound middle frame cross-member 30. The seals 20 therefore inhibit sound from passing through the partition 10. The seals 20 can also be used, if they are translucent or opaque, to prevent the transmission of light through the partition 10. The seals 20 can be made of an elastomer or any other suitable material.
In the illustrated example, the attachment members 18 comprise upper attachment members 18a connected to the upper channel member 62 of the cover member 16 and lower channel members 18b connected to the lower channel members 65 of the cover member 16. The upper attachment members 18a comprise spring clips (
The illustrated protruding U-shaped portion 82a of the upper attachment member 18a extends substantially perpendicularly from an upper edge 90a of the plate 80a, with the protruding U-shaped portion 82a opening rearwardly. The U-shaped portion 82a includes a lower sheet 91a, an upper sheet 92a, a pair of U-shaped leaf spring locking arms 93a connecting the lower sheet 91a and the upper sheet 92a, and an upstanding connecting flange 96a. Although two leaf spring locking arms 93a are shown, it is contemplated that only one or several leaf spring locking arms could be used. The lower sheet 91a includes a first portion 94a extending downward and rearward from the top edge 90a of the plate 80a and a second portion 97a extending upward and rearward from the first portion 94a. As seen in
In the illustrated example, the upstanding connecting flange 96a of the upper attachment member 18a has an inverted U-shape as viewed from the front of the upper attachment member 18a and extends upward from the pair of U-shaped notch members 105a. The upstanding connecting flange 96a includes a cross portion 100a having an inverted L-shaped cross-section. The cross portion 100a includes a substantially horizontal section 102a extending rearward. The protruding U-shaped portion 82a assists in connecting the cover member 16 to the frame 12.
The illustrated lower attachment members 18b (
In the illustrated example, the protruding U-shaped portion 82b of the lower attachment member 18b extends from the lower edge 90b of the plate 80b, with the protruding U-shaped portion 82b opening rearwardly. The U-shaped portion 82b includes a lower sheet 91b, an upper sheet 92b, a pair of U-shaped leaf spring locking arms 93b connecting the lower sheet 91b and the upper sheet 92b. The upper sheet 92b extends downwardly and forwardly from the lower edge 90b of the sheet 91b. The pair of U-shaped leaf spring locking arms 93b extend downward from an edge of the upper sheet 92b opposite to the lower edge 90b of the sheet 91b. The lower sheet 91b is also connected to the pair of U-shaped leaf spring locking arms 93b and is located at a position below the upper sheet 92b. The lower sheet 91b includes an elongated notch member 105b extending from a side of the lower sheet 91b opposite to the pair of U-shaped leaf spring locking arms 93b. A tab 103b extends downwardly from the elongated notch member 105b. The protruding U-shaped portion 82b assists in connecting the cover member 16 to the frame 12.
In the preferred embodiment, the upper attachment members 18a are connected to the cover member 16 by first inserting the side flange 84a with the longer second leg 87a fully into one of the slots 70 in the intermediate L-shaped flange 64 of the upper channel member 62. Once the side flange 84a with the longer second leg 87a is fully inserted into one of the slots 70, the side flange 84a with the shorter second leg 87a can fit into the other slot 70 (see FIG. 10). The panel section 81a will be flush against the intermediate L-shaped flange 64 at this point. The upper attachment member 18a is then shifted laterally in the direction of the side flange 84a with the shorter second leg 87a until the first leg 95a of the side flange 84a with the shorter second leg 87a abuts against an outside edge 71 of the slot 70. As seen in
In the preferred embodiment, the lower attachment members 18b are connected to the cover member 16 in the same manner as the upper attachment members 18a. Therefore, the lower attachment members 18b are connected to the cover member 16 by first inserting the side flange 84b with the longer second leg 87b fully into one of the slots 70 in the intermediate L-shaped flange 64 of the lower channel member 65. Once the side flange 84b with the longer second leg 87b is fully inserted into one of the slots 70, the side flange 84b with the shorter second leg 87b can fit into the other slot 70. The panel section 81b will be flush against the intermediate L-shaped flange 64 at this point. The lower attachment member 18b is then shifted laterally in the direction of the side flange 84b with the shorter second leg 87b until the first leg 95b of the side flange 84b with the shorter second leg 87b abuts against an outside edge of the slot 70. When the side flange 84b with the shorter second leg 87b is fully inserted into the slot 70, the forwardly and outwardly extending detent 89b extending from the central portion of the longer second leg 87b will snap outward to abut against an outside edge of the other of the slots 70 to maintain the lower attachment member 18b in position in the cover member 16. Because the slots 70 are angled as discussed above, the lower attachment members 18b will only fit into the slots 70 with the protruding U-shaped sections 82b of the lower attachment members 18b in the proper position for connecting the cover member 16 to the frame 12. Therefore, the two lower attachment members 18b adjacent the bottom edge of the cover member 16 will have the protruding U-shaped section 82b below the central plate 80b.
The illustrated upper attachment members 18a connect the cover member 16 to the frame 12 by inserting the protruding U-shaped sections 82a into the oval-shaped windows 48 on the frame 12 (see FIGS. 13 and 14). In the illustrated example, one cover member 16 will enclose an upper portion 113 (see
The illustrated cover member 16 is connected to the frame by first inserting the protruding U-shaped portions 82 of the lower attachment members 18b into the oval-shaped windows 48 in either the front face 36 or the back face of the lower frame cross member to enclose the lower portion 114 of the frame 12, or the upper front face 40 or the upper back face 41 of the middle compound frame cross member to enclose the upper portion 113 of the frame 12 (see, e.g. FIG. 13). As the protruding U-shaped portions 82b of the lower attachment members 18b are inserted into the oval-shaped windows 48, the upper sheet 92b and the lower sheet 91b have a maximum distance therebetween longer than the distance between the top edge 58 and the bottom edge 50 of the oval-shaped windows 48. Therefore, the upper sheet 92b and the lower sheet 91b will flex towards each other, with the pair of U-shaped leaf spring locking arms 93b biasing the upper sheet 92b and the lower sheet 91b away from each other. When the protruding U-shaped portion 82b of the lower attachment member 18b is fully inserted into the oval-shaped windows 48, the lower sheet 91b will snap downward and the bottom edge 50 of the oval-shaped window 48 will rest in the elongate notch member 105b. Furthermore, the upper sheet 92b will snap upward.
The illustrated cover member 16 is then fully attached to the frame 12 by rotating an upper portion of the cover member 16 towards the frame 12 to insert the upper attachment members 18a into the frame 12. The upper attachment members 18a connect the cover member 16 to the frame 12 by first inserting the protruding U-shaped portions 82a of the upper attachment members 18a into the oval-shaped windows 48 to connect the cover member 16 to the frame 12 (FIGS. 13 and 14). As the protruding U-shaped portions 82a of the upper attachment members 18a are inserted into the oval-shaped windows 48, the upper sheet 92a and the lower sheet 91a have a maximum distance therebetween longer than the distance between the top edge 58 and the bottom edge 50 of the oval-shaped windows 48. Therefore, the upper sheet 92a and the lower sheet 91a will flex towards each other, with the pair of U-shaped leaf spring locking arms 93a biasing the upper sheet 92a and the lower sheet 91a away from each other. When the protruding U-shaped portion 82a of the upper attachment member 18a is fully inserted into the oval-shaped windows 48, the upper sheet 92a will snap upward and the top edge 58 of the oval-shaped window 48 will rest in the pair of U-shaped notch members 105a. Likewise, the lower sheet 91a will snap downward and the bottom edge 50 of the oval-shaped window 48 will rest in the downwardly opening channel 99a of the upper attachment member 18a. Furthermore, the tab 103a will snap behind the respective face of the frame cross-member. Therefore, the upper attachment members 18a will be positively locked within the oval-shaped windows 48 to connect the cover member 16 to the frame 12. Accordingly, the cover member 16 will be connected to the frame 12 by the upper attachment members 18a and the elongated notch 105b of the lower attachment members 18b. As described in more detail below, the upstanding connecting flange 96a is depressed to remove the upper attachment members 18a from the oval-shaped windows 48.
In the illustrated example, a tool 1000 preferably is used to remove the upper attachment members 18a from the oval-shaped windows 48. The tool 1000 (
The illustrated lower attachment members 18b are thereafter removed from the oval-shaped windows 48 by rotating the upper portion of the cover member 16 away from the frame. As seen in
The reference numeral 16c (
In the illustrated example, the side rails 122 each have a stepped cross-section including an outside portion 128, an intermediate portion 130 substantially perpendicular to the outside portion 128 and an inside portion 136 substantially perpendicular to the intermediate portion 130. The outside portion 128 and the intermediate portion 130 extend for the length of the side rails 122. However, the inside portion 136 has a length shorter than the intermediate portion 130 and the outside portion 128 with top and bottom ends of the inside portion 136 equally distant from the ends of the side rails 122. The outside portion 128, intermediate portion 130, and the inside portion 136 abut and have portions connected to the top rail 124 and the bottom rail 126.
The illustrated top rail 124 and bottom rail 126 are identical, with the bottom rail 126 being positioned in an opposite orientation to the top rail 124. Only the top rail 124 will be described, with the understanding that the bottom rail 126 includes the same elements in an opposite orientation (e.g., upper for the top equals lower for the bottom). The top rail 124 is similar to the side rails 122 and includes an upper horizontal portion 138, a first vertical portion 140, a middle horizontal portion 142, a second vertical portion 144 and a lower horizontal portion 146. The upper horizontal portion 138 preferably is bent over in a tight U-shape to provide strength for the top rail 124. The second vertical portion 144 has a bent over bottom section 148 that is also bent over in a tight U-shape and extends first downward from the horizontal portion 142 and then upward. The second vertical portion 144 also has a pair of slots 70c located adjacent the ends of the second vertical portion 144 and above the bent over bottom section 148. A support flange 132 is attached behind the first vertical flange portion 140 of the top rail 124 and includes an L-shaped lower portion 134 attached behind the bent over bottom section 148 of the second vertical portion 144. Therefore, the middle horizontal portion 142, the second vertical portion 144 and the support flange 132 define a rectangular tube 131. Similar to the side rails 122, the upper horizontal portion 138 and the first vertical portion 140 extend for the length of the top rail 124. Furthermore, the middle horizontal portion 142, the second vertical portion 144 and the lower horizontal portion 146 have a length shorter than the upper horizontal portion 138 and the first vertical portion 140, with side ends equally distant from the ends of the top rail 124. In the preferred embodiment, the top rail 124 is connected to the side rails 122 by placing the upper horizontal portion 138 of the top rail 124 over the top edge of the outside portion 128 of the side rails 122 and overlapping the first intermediate portion 130 of the side rails 122 over the side face of the first vertical portion 140 of the top rail 124.
The attachment members 18c are connected to the cover member 16c by inserting each attachment member 18c into one of the pair of slots 70s as described in the first embodiment. The lower attachment members 18b are connected to the bottom rail 126 in a like manner. Furthermore, the seal 20c is connected to the lower horizontal portion 146 in the same manner as the connection between the seal 20 and the lower flange 68 of the first embodiment. The cover member 16c can then be attached to the frame 12c as discussed above, with the resilient flap 22c of the seal 20c engaging the horizontal surface 14c of the frame 12c.
The reference numeral 10d (
In the illustrated example, the protruding U-shaped section 82d of the lower attachment member 18d is angled downward such that a portion of the protruding U-shaped section 82d adjacent the pair of U-shaped leaf spring locking arms 93d and an edge of the lower sheet 91d abuts an interior surface 57 of the compound middle frame cross-member 30d above the inwardly facing channel 51d. As the cover member 16d is rotated outward, the L-shaped tab 109d of the lower attachment member 18d will create a pivot point 2000d that the cover member 16d will rotate about. The pivot point 2000d will assist the upper sheet 91d of the lower attachment members 18d to move away from the top edge 58d of the oval-shaped windows 48d, thereby allowing the protruding U-shaped portion 82d of the lower attachment members 18d to be removed from the oval-shaped windows 48d. In the illustrated example, the pivot point 2000d is located at a corner defined by the upper back face 41d and the inwardly facing channel 51d.
The above description is considered that of the preferred embodiments only. Modification of the invention will occur to those skilled in the art and to those who make or use the invention. For example, it is contemplated that a lock member could be attached to the cover member 16 for locking the cover member 16 to the frame 12 when the cover member 16 is connected to the frame 12. The lock member could extend from a rear face of the cover member 16 and engage a bottom face of one of the cross-members of the frame. Therefore, it is understood that the embodiments shown in the drawings and described above are merely for illustrative purposes and not intended to limit the scope of the invention, which is defined by the following claims as interpreted according to the principles of patent law, including the doctrine of equivalents.
